[libvirt-users] question about libvirt network Xml
by Robert Li (baoli) 24 Oct '14

24 Oct '14

Hi, I’m an openstack developer trying to use Assignment from a pool of SRIOV VFs in a libvirt <network> definition from this link http://wiki.libvirt.org/page/Networking My question is is it possible for nova (the openstack compute) to know which VF out of the pool will be allocated to a VM before it invokes libvirt to launch it? Thanks In advance, Robert

[libvirt-users] Public IP addresses are not logged in VMs
by Roland Giesler 24 Oct '14

24 Oct '14

Anyone that can help me solve this one? I have around 4 VM's on a server and the network is bridged and a /28 public IP range assigned to it . When a client connects to one of the VM's, they all always log the address of the host server, never the client ip address. How can I fix this? Things I have investigated: 1. Switch to routed network. That would not help, since I would firstly need another public IP subnet to route to (the virtual machines). 2. Could have something to do with the libvirt firewall rules, but they are default, I didn't touch them I have read many posts in forums and websites, but none make any mention of this behaviour. Help would really be great!

[libvirt-users] Libvirt with containers
by Anjali Kulkarni 20 Oct '14

20 Oct '14

Hi, I am trying to define a container using libvirt, and I need to allow access of the device /dev/uio0 on the host on the container as well. That is, I have the following line in the container config file: lxc.mount.entry = /dev/uio0 dev/uio0 none bind,create=file lxc.cgroup.devices.allow = c 249:1 rwm And I want to add it in the libvirt XML file for the container. I tried something like: <filesystem accessmode="passthrough" type="mount"> <source file="/dev/uio0" /> <target dir="/dev/uio0" /> </filesystem> But it gave me error: root# virsh -c lxc:/// define lxc_v.xml error: Failed to define domain from lxc_v.xml error: missing source information for device /dev/uio0 Can someone pls help, how I can add the /dev/uio0 to the xml file? Thanks Anjali

[libvirt-users] HostDevev SCSI Devices
by Fl＠sh 20 Oct '14

20 Oct '14

http://libvirt.org/formatdomain.html#elementsHostDevSubsys At this description used "drive"-typed address for SCSI. But when i get xml-description of scsi-devices by <code> unsigned int flags = VIR_CONNECT_LIST_NODE_DEVICES_CAP_SCSI_HOST ; int ret = virConnectListAllNodeDevices (currWorkConnect, &nodeDevices, flags); then get by virNodeDeviceGetXMLDesc(nodeDevices[i], 0)); </code> i have same: <device> <name>scsi_host2</name> <path>/sys/devices/pci0000:00/0000:00:1f.2/ata3/host2</path> <parent>pci_0000_00_1f_2</parent> <capability type='scsi_host'> <host>2</host> <unique_id>3</unique_id> </capability> </device> . I understand that this device description contains a "pci"-typed addresses. Then where to get the "scsi"-typed address? -- Fl@sh

[libvirt-users] drive-backup command permission denied.. and need some clarification
by Jd 16 Oct '14

16 Oct '14

Hi * Trying to get drive-backup command, getting permission denied. :( sudo virsh qemu-monitor-command --hmp my-instance --cmd drive_backup drive-virtio-disk0 /tmp/foo.vda.img Looks like apparmor issue. What can I modify to make this work ? * Couple of other questions drive-backup : * The doc seems to claim that it gives a point in time copy of the drive. So I assume that no need to take any snapshot etc.. and merge back in. * does it internally use snapshot ? Does this hook in to doing fsfreeze and unfreeze using guest agent and does it automagically ? I do not see any options here. * Suppose I have base <-- sn1 --<-- sn2 (QEMU active) . does it take data from sn2 only ? or base+sn1+sn2 .. full drive and creates a new qcow2 sparse file. Thanks /Jd

[libvirt-users] Fwd: Hotadd memory and hotplug cpu
by ra va 16 Oct '14

16 Oct '14

Hello, Does KVM support hotadd memory and hot-plug cpu? I checked it using the virsh command but I can only increase the memory to the maximum memory that is initially set But setmaxmem command is failing. Which means this require a reboot of the guest # virsh setmaxmem 4 1048576 error: Unable to change MaxMemorySize error: Requested operation is not valid: cannot resize the maximum memory on an active domain #virsh setvcpus 4 4 error: internal error: unable to execute QEMU command 'cpu-add': Not supported Thanks ravargs

[libvirt-users] VGA as vfio-pci and vnc server's blank/black display
by lejeczek 15 Oct '14

15 Oct '14

hi, I'm having a Radeon as vfio-pci, which seems to work perfectly fine, but... Qemu's model type='vga' gets "exlaimed" in win2k8's Device Manager with: " Windows has stopped this device because it has reported problems. (Code 43) " Now, that does not bother me that much as all I need on regular basis is RDP but VNC connection gets me nowhere. I get blank/black screen, it connects without errors/problems but nothing more. I know you would say VGA passthrough is only supported for very few VGA adapters but is the situation I describe normal/expected? regards

[libvirt-users] Fixed Public IP to VM Guest
by Joel A Divekar 13 Oct '14

13 Oct '14

Hi All We have setup a Centos7 host server with KVM and have created multiple VM running Ubuntu 14.04 using virt-manager. All VMs are having forward mode as "NAT" and using internal DHCP IP address 192.168.122.x series and we gave them fixed ips based on their mac address. Now all these VMs are able to access Internet and able to run update on all these guest OS. But these VMs are web and API servers and they are required to be accessible from Internet. We have pool of public IPs and have assigned host with one public IP for example, we have pool like 192.168.111.1 to 192.168.111.25. We have assigned 192.168.111.2 to Host server and would like to assign 192.168.111.3 to Webserver and 192.168.111.4 to API server. So we changed our virsh network settings from default to routed as <forward mode='route' dev='em1'> and struggling to configure fixed IPs for our VMs. We would like to do exactly as mentioned in this link https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/ht… We have been struggling with this for last 3 days and no luck. Please can anybody guide us. Regards Joel Divekar

[libvirt-users] is memoryBacking support 'share' and 'mem-path' parameter
by Linhaifeng 09 Oct '14

09 Oct '14

Hi, I want to use this qemu command '-object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on' with libvirt but i can't find the 'mem-path' and 'share' in the documentation. because the vhost-user backend based on 'share=on' parameter and libvirt support vhostuser i guess there maybe another way to support this parameter? this is my xml: <cpu> <numa> <cell id='0' cpus='0' memory='1048576' memAccess='shared'/> <cell id='1' cpus='1' memory='1048576' memAccess='shared'/> </numa> </cpu> <memoryBacking> <hugepages> <page size="2" unit="M" nodeset="0,1"/> </hugepages>   </memoryBacking> <interface type='vhostuser'> <mac address='52:54:00:3b:83:1a'/> <source type='unix' path='/path/port1' mode='client'/> <model type='virtio'/> </interface> <interface type='vhostuser'> <mac address='52:54:00:3b:83:1b'/> <source type='unix' path='/path/port2' mode='client'/> <model type='virtio'/> </interface> when i create the VM the qemu command is like this without 'share=on' parameter: -object memory-backend-file,prealloc=yes,mem-path=/dev/hugepages/libvirt/qemu,size=1024M,id=ram-node0 -numa node,nodeid=0,cpus=0,memdev=ram-node0 -object memory-backend-file,prealloc=yes,mem-path=/dev/hugepages/libvirt/qemu,size=1024M,id=ram-node1 -numa node,nodeid=1,cpus=1,memdev=ram-node1

[libvirt-users] Question about vnc connection password set to empty
by Wei Zhang 09 Oct '14

09 Oct '14

Hello, everybody here I have a question about graphical buffers for rhel7. Thanks so much in advance who can give me some suggestions about that. When I try to do regression for bug859317(https://bugzilla.redhat.com/show_bug.cgi?id=859317) on RHEL7， I found that guest could be connected success with virt-viewer when set/update the graphics passwd to empty. But according to comment 2 in this bug, libvirt will blocks all access to the VNC server when set a password to empty. So could you please help us check is it acceptable on RHEL7? Below is my test steps on RHEL7: Version-Release number of selected component (if applicable): libvirt-1.2.8-3.el7.x86_64 qemu-kvm-rhev-2.1.0-5.el7.x86_64 kernel-3.10.0-150.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. Define guest with a graphics device like: ......................................... <graphics type='vnc' port='-1' autoport='yes' passwd=""/> ......................................... 2. Connecting with vncviewer or virt-viewer . # virsh start dom2 # virsh dumpxml dom2 --security-info |grep graphics <graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1' passwd=''> </graphics> # virt-viewer dom2 connect the guest success with empty password 3. The problem can be reproduced when changed the graphics passwd from an non-empty to an empty # virsh dumpxml dom2 --security-info |grep graphics <graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1' passwd='123'> </graphics> # cat change-passwd.xml <graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1' passwd=''/> # virsh update-device dom2 change-passwd.xml # virsh dumpxml dom2 --security-info |grep graphics <graphics type='vnc' port='5900' autoport='yes' listen='127.0.0.1' passwd=''> </graphics> login the guest with virt-viewer command # virt-viewer testks also can connect the guest dom2 success with empty password 4. I produce the same steps on RHEL6.6 libvirt-0.10.2-46.el6.x86_64, the guest can not be connected when set graphics vnc password to empty, the same result with bug 859317. Actual results: we can login the guest when set the graphics passwd empty Expected results: I am not sure what is the right behaviour for RHEL7? thank

[libvirt-users] virsh net-start default fails
by David Roundy 08 Oct '14

08 Oct '14

Hi all, I'm getting an error, and have failed to succeed in googling for help with it. I have an old VM that I created a while back (at least one reboot ago, possibly a kernel upgrade ago), and am now finding that it won't start due to a lack of the 'default' network. When I look for how to fix this, everyone seems to agree on the command: # virsh net-start default error: failed to get network 'default' error: An error occurred, but the cause is unknown But this fails. A natural next check would be to use net-list: # virsh net-list --all Name State Autostart ----------------------------------------- Which demonstrates that the 'default' network is unknown. I'm certain that it used to exist, and the file /var/lib/libvirt/network/default.xml does exist, claims to be autogenerated and looks reasonable. I am at a loss as to how to debug this further. Any suggestions? -- David Roundy

hi everybody a qemu-kvm guest gets 16 cpus and Windows in "Device Manager" sees all sixteeen but "Task Manager" shows only 4, the same "System" properties say "(4 processors)" I'd like to learn a bit about this - is it some sort of "resources management" on the libvirt/qemu causing this? And what does it do to a guest performance-wise side? it's on Scientific L 7, qemu-kvm-1.5.3-60.el7_0.7.x86_64 libvirt-1.1.1-29.el7_0.1.x86_64 regards P.

[libvirt-users] libvirt-sandbox on Fedora 21
by Gene Czarcinski 07 Oct '14

07 Oct '14

It sure would be nice if someone who knows what they are doing took a look at this problem: https://bugzilla.redhat.com/show_bug.cgi?id=1135762 The current situation on Fedora 21 is that virt-sandbox and virt-sandbox-service simply do not work if a network is defined (e.g., -N address-192.168.1.1/34). I would give dhcp as an example but to work, that needs to patch I submitted in another BZ report. Since both virt-sandbox -c lxc:/// -N <network>,source=default and doing systemctl start <sandbox> result in the same error and since I am running the fedora-virt-preview rpms and the failure *does not* occur on Fedora 20 but *does* occur on Fedora 21, I have to assume that the problem is not directly in libvirt. However, determining what/where the problem really is, is stretching my abilities a bit too far ... help!! Gene

[libvirt-users] Virtual gaming/workstation desktops using KVM VGA passthrough?

Dear List, Recently I read an article [1] about how to use KVM and VGA passthrough to create multiple GPU accelerated VM's for use in gaming or as virtual workstations: [1] http://www.pugetsystems.com/labs/articles/Multiheaded-NVIDIA-Gaming-using-U… I'm planning on building a KVM workstation to do this using CentOS 7 or Ubuntu 14.04 LTS as the base virtualization host and then an Intel Xeon CPU and two Nvidia GeForce GTX 750's as GPU's for the virtual machines. I'm really new to this sort of GPU passthrough on KVM and am wondering if anyone has any advice or has done this before? Thank you!

[libvirt-users] Assigning IPv6 address to guest
by The Cop 05 Oct '14

05 Oct '14

Hello, I am trying to assign an IPv6 address to one of my guests. I followed the following guide, unsuccessfully: https://www.berrange.com/posts/2011/06/16/providing-ipv6-connectivity-to-vi… . I have the following config files: dumpxml of the guest `deb`: http://sprunge.us/iUef net-dumpxml of network `default`: http://sprunge.us/WTfH net-dumpxml of network `ip6`: http://sprunge.us/YEXc Host: ifconfig: http://sprunge.us/cJOg Routing table: IPv6: http://sprunge.us/GChZ IPv4: http://sprunge.us/dACN /etc/network/interfaces: http://sprunge.us/fHcf /var/lib/libvirt/radvd/ip6-radvd.conf: http://sprunge.us/JcfF ip6tables: http://sprunge.us/JGBG uname -a: http://sprunge.us/acFF Guest: ifconfig: http://sprunge.us/JIFN Routing table: IPv6: http://sprunge.us/ZPfT IPv4: http://sprunge.us/gbXA /etc/network/interfaces: http://sprunge.us/ZaBB uname -a: http://sprunge.us/CFFL Both machines are running Debian Wheezy. virsh version is 0.9.12.3. The IP address I'm trying to assign to the guest is "2607:5300:60:1156::2/64". Forgive me if I'm making some trivial mistake, but this is more or less the first time I'm productively using IPv6. Thanks

[libvirt-users] pxe boot of new xen VMs
by Alvin Starr 03 Oct '14

03 Oct '14

When I try to pxe boot a new VM through lvm and libxl I find about 1 in 10 times the pxe requests will be acknlwledged but if I go into the interacive ipxe screens it will boot every time. Is it possible that the network configuration is not built when the VM starts trying to get its pxe address? -- Alvin Starr || voice: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin(a)netvel.net ||
